ETI
(
adjustable

trip
only
)
are
designed
for
use
in
welding
circuits
,
motor
circuits
and
combination
starters
where
short
circuit
protection
only
is
required
.
When
used
in
combination
starters
,
they
serve
in
conjunction
with
motor
protective
relays
to
offer
complete
protection
.
The
relays
guard
against
motor
overloads
and
the
circuit
breaker
provides
short
circuit
protection
.

Circuit
Breaker
Operation
With
the
mechanism
latched
and
the
contacts
open
,
the
oper
-
ating
handle
will
be
in
the
OFF
position
.
Moving
the
handle
to
the
ON
position
closes
the
contacts
and
establishes
a
circuit
through
the
breaker
.
Under
overload
or
short
circuit
conditions
sufficient
to
automatically
trip
or
open
the
breaker
,
the
oper
-
ating
handle
moves
to
a
position
between
ON
and
OFF
.
To
relatch
the
circuit
breaker
after
automatic
operation
,
move
the
operating
handle
to
the
extreme
OFF
position
.
The
circuit
breaker
is
now
ready
for
reclosing
.
The
overcenter
toggle
mechanism
is
trip
free
of
the
operating
handle
.
The
circuit
breaker
,
therefore
,
cannot
be
held
closed
by
means
of
the
handle
should
a
tripping
condition
exist
.
After
automatic
operation
,
the
handle
assumes
an
intermediate
position
between
ON
and
OFF
,
displaying
a
clear
indication
of
tripping
.

Maintenance
Experience
has
shown
that
properly
applied
molded
case
cir
-
cuit
breakers
normally
do
not
require
maintenance
.
However
,
some
industrial
users
may
choose
to
establish
an
inspection
and
maintenance
procedure
to
be
carried
out
on
a
regular
basis
.
For
detailed
information
,
consult
applicable
NEMA
publications
or
